Minimum speed limits must be obeyed except under which of the following conditions?

Minimum speed limits are established to ensure the safe and efficient flow of traffic. However, these limits can be disregarded when road or traffic conditions do not permit safe travel at that minimum speed. For instance, if there is heavy traffic congestion, road construction, or any other factor that may necessitate driving slower for safety reasons, drivers are permitted to drive below the minimum speed limit.

The rationale is that the primary goal of minimum speed limits is to maintain a flow of traffic that allows for safe driving patterns; thus, in conditions where it may be hazardous to adhere to these limits, safety takes precedence. It is vital for drivers to assess their immediate environment and operate their vehicles under conditions that ensure safety, even if it means falling below the established minimum speed limit.
